Klein ISD Sports Fundraising

So we are relatively new to the area coming from the east coast. Our son is playing on one of the ISD football teams. The athletics departments at the schools here when it comes to funding are the equivalent to the Taj Mahal compared to schools in the southeast. What I don’t understand is based on the high taxes that we pay here how is that the school has a mandatory fundraiser where my kid is required to give 20 plus names and email addresses to a soliciting group that will harass family and friends non stop to get $500 per kid out of them? Where does the tax money go besides these insane football stadiums around here? The coach pulled 23 kids in the gym today and tells them that they are leaders and they are setting a bad example by not raising money and helping towards uniforms and helmets. You guys haven’t done jack to help. I’m sorry not every person has a large group of family and friends that has spare money laying around to give away and receive nothing in return. Is this a common practice at all the ISD’s in the area?
